From Wikipedia:

Lincoln Cathedral (in full The Cathedral Church of the Blessed Virgin Mary of Lincoln, or sometimes St. Mary's Cathedral) is a cathedral located in Lincoln in England and seat of the Bishop of Lincoln in the Church of England. Building commenced in 1088 and continued in several phases throughout the medieval period.

The cathedral is located in Lincolnshire, England. It is quite large and tall, which you will feel if you decide to take Tower Tour. However, if you are out of shape the tour may not be the best idea. But then, the view from the tower is quite nice. What else? Oh yes, there is an admission fee, and a small castle next to the cathedral. Also, while walking up to the cathedral you can admire Lincoln itself, which is really pretty town.

Castle is small and there is almost nothing to see there, but it is just next to the cathedral which makes it convenient for visiting.

There is not much to say about it. It is small, quiet town like many other in England. There are some trails for sightseeing, but the best part you will see while climbing up to the cathedral.
